	There's also a pretty decent coverage of the topic in Stephen K.
O'Brien's "Turbo Pascal - Advanced Programmer's Guide" (Borland-Osbourne,
ISBN 0-07-881420-0).  Included is a TSR unit (as well as several other units
for various purposes) that is pretty thorough in its handling of TSR's, both
from DOS and from within applications.

	I have used it many times, and have only one complaint about it:
perhaps because it _is_ so thorough, it is also fairly large.  A TSR that
does nothing more than enter and exit (i.e., not even a 'hello' message -
simply "begin {do nothing} end;") takes up a fair chunk of memory, about
20K, if memory serves.  This can cause problems if you frequently run stuff
like Ventura or what-have-you, and still want access to your MRP.

	"Just thought you'd like to know..."
